Finding A Solution To Problems

• The solution to a problem involves executing a

series of actions in a specific order.

• The procedure for solving a problem expressed in

terms of:

1. The actions to be executed, and

2. The order in which they are to be executed

Is called an algorithm.

Control Structures

CONTROL STRUCTURES FOR THE ORDER OF

EXECUTION ARE:

• SEQUENCE

• SELECTION

• REPETITION

• ABSTRACTION
